I '0 all whom it may concern: I

. Be it known that we, DANIEL A. AUMAN and GEORGE C. AUMAN, residing at Reading, in the county of Berks and State of Pennsylvania, have invented a new and use ful Improvement in Railroad Rails, of which the following 'is a specification.

This invention relates to a compound, sectional railroad rail, in which the tread portion can be laced without disturbing the base, in whic no fish plates or other forms of joint connections are required, and in which the upper tread portion can be fitted into position so as to break joint with the lower portion, and can be secured thereto Without drilling bolt openings in the said tread portion, or without having to match bolt holes formed respectively in the two sections.

WVith these objects in view the invention consists imthe novel features of construction hereinafter described. pointed out in the claim and shown in the accompanying drawings, in which Figure 1 is a perspective view showing an end portion of the upper section, the lower portion of the base being shown in section. Fig. 2 is a transverse section through a conr plete rail.

In these drawings 1, represents the base portion the web 2 of which is thickened and is provided with a vertical longitudinal groove 3, opening upwardly. The upper edges of this base section 1. are slightly bev- 35'eled to fit the under face of the upper tread section 4. Said tread section is also pro- )jid'ed with a web portion 5. which tits snugly within the groove 3, resting upon the bottom of said groove. The web 5 is longi- .40 tudinally grooved upon each side as shown Specification 01' Letters Iatent.

at (i, and suitable set screws 7, are threaded into suitable openings formed in the web 2, of the base and those set screws enter the grooves (l, and lock the upper section 4, in place. The set screws are in turn locked in place by suitable locking nuts 8.

It will be understood that the base section and the upper section of the rail break joints so that a practically continuous rail is formed and it will also be understood that the set screws upon one side of the rail are onset with respect to those on the other side. By reason of the continuous grooves (3, the ripper sections of the rail can be dropped into place and locked at any point with re spect to the base section. This is not the case where (JOLIIPOlllltl rails are secured together by bolts passing entirely tlirough both sections as it is necessary to match the bolt openings, unless new bolt holes are especially drilled at. the time the rails are titted together. A rail constructed as shown by us can be laid and replaced with much less labor than those compound rails with which we are fan'iiliar.

\Vhat we claim is:

A compound rail, com 'irising a base section longitudinally grooved, a tread section having a web adapted to tit into the groove of the basesection, said web having longitudinal grooves upon its opposite side faces. and set screws carried by each side of the base section and engaging the upper sections in the horizontal plane of said grooves, as and for the purpose set forth.
